walked down to the water last week the way I do most mornings, and it felt off. Not rough, not cold. Warm in a way that made me pause before I got in. Turns out I wasn’t imagining it.
Ocean surface temperatures hit a record high in June. Two separate arms of the EU’s Copernicus program checked the numbers independently and landed in the same place. And now there’s a marine heatwave sitting across the Pacific that covers about 13.5 percent of the entire surface of the earth. More than eight times the size of the continental United States. It stretches from the Philippines to Peru, up toward Hawaiʻi and California. I live inside that map.
It didn’t arrive all at once. Two smaller heatwaves, one in the North Pacific and one along the equator, drifted toward each other and merged into this. Scientists are calling it “ominous.” I’d call it that too, except the word feels too small once you picture the actual size of the thing.
So what does a warmer ocean actually do. It doesn’t just sit there being warm. Warm water feeds storms, and it holds onto heat long after the summer that made it. Climate scientist Dillon Amaya put it plainly: months and months of this warmth could mean stark impacts this winter and into next spring. Not a headline that fades in September. A slow release, months out.
I think about the reef when I read this. I think about the fish that don’t have the option of walking down to a different shoreline when their water gets uncomfortable. Marine heatwaves aren’t abstract to the creatures living in them. They’re a survival math problem, and a lot of species are losing it quietly, out of view.
Here’s my honest opinion. We talk about ocean warming like it’s a future threat, something on a graph pointed at a decade we haven’t reached yet. It isn’t. It’s happening under the boats leaving Honolulu harbor this morning. The gap between “the ocean is warming” and “the ocean is warm” has basically closed, and most of us are still speaking in the future tense out of habit.
The South-West Pacific has been living this pattern longer than most places. Longer, more frequent, more intense heatwaves, and real consequences for the communities whose lives run through these waters. Not new information for the people who fish these waters for a living. New information mostly for the people who only think about the ocean when it’s postcard-flat and blue.
I don’t have a tidy fix to offer here. I’m not sure anyone does, not one that fits in a paragraph. What I have is the water, warmer under my hands than it should be in July, and the discipline of paying attention to that instead of looking away.
So I’ll keep walking down to the shore. I’ll keep noticing when it feels wrong. That’s a small thing. But attention is where every larger thing starts.
The tide comes in regardless of what we decide to do about any of this. I’d like it to come in a little cooler, is all.
Much love, t
